By the look of those messages the app has been updated, and now wants to update the superuser module that's been added to the system. SuperSU is an app that is used to control root access. hacked to enable you to run user apps with system privileges. Your phone has been "rooted" by a previous owner, i.e.
That means that your phone's hardware will be different from a UK model and you can only use software that was written for that model. Sprint is a US carrier, and moreover is one that uses a technology called "CDMA", which is used only by a couple of North American carriers and almost nobody else. But you'll need to do a reset as part of that, so backups are going to be important this way as well.Ĭlick to expand.OK, from the software build number you quoted I think you've got a Sprint model (I Googled "HTC M9 3.41.651.4" and all of the results refer to the Sprint M9). If you have a custom ROM another approach might be to find a better ROM. Note that returning to stock via an RUU will erase the phone, so back up everything first. Bootloader and baseband version numbers, which you should be able to read off the bootloader screen, will also be useful because an RUU cannot downgrade the firmware.
Otherwise the way to find out for sure is to install an application called "fastboot" on a computer (you should be able to find it form the site or indeed many others - a web search will do this), then put the phone in fastboot or download mode (I think it's called "download" on the M9), connect to the computer via usb, open a command line/terminal on the computer, cd to the directory you installed fastboot to and try the command "fastboot getvar all" and look for the "cidnum" value. But unless the phone's software security has been disabled (S-Off - look at the top of the bootloader screen for S-On or S-Off) you would need an RUU that's designed for the particular cidnum (Customer ID number), which means the region/carrier the phone was originally sold to.
So can you tell us which of these is the case, and especially whether it has modified firmware (custom ROM or recovery)?įor returning to stock, you need a ROM Upgrade Utility (RUU), a HTC application that reflashes a phone to stock. But you also say you want to return it "to stock", which means that the firmware has been modified. If it was a carrier variant that might explain the lack of updates, as it may need to be connected to the original network to get them. Apparently, the temperature doesn’t exceed 40☌ when the phone is charging.Do you know exactly what M9 model it is, and what country/region/carrier it was originally sold for? According to the user, the device now runs 10☌ lower, drastically improving performance. After the user applied the update, he reported the news that everyone wanted to hear, better performance and lower temperatures. Users over at XDA forums have reported a new OTA software update (v1.40.401.5) where the changelog includes thermal improvements and camera improvements.
A software update went public a few weeks ago which didn’t fix issue. Since the phone has been on the market for a few months, HTC developers have worked for a fix to solve the One M9 overheating issue. There are better news about HTC One M9 though. A few days ago, Sony acknowledged that there is indeed a serious problem with high temperatures and they are working on a fix which will be released this summer. Recently, Sony released the Sony Xperia Z4/Z3+ with the Snapdragon 810 chipset and reports about the device reaching high temperatures surfaced just a few days later.
